.. COMMON ANCESTRY: • • What is a vestigial structure? o What is a homologous structure? o • What is an analogous structure? o I I • What does it mean when the embryos of different same? • Complete t he f oIIoWingc har t : organisms look the - Are the organisms closely or remotely related? Homologous Structure I Analogous Structure EVOLUTION; • What is adaptive radiation? o • What is divergent evolution? o • What is convergent evolution? o • What is coevolution? o ! • complete t he f oIIoWingchar t : Type of Environment Two or more species Examples Convergent Divergent • What causes these organisms to become more similar or more different? o MORE: • What do we call the collection of genes for all the traits in a population? o • What is a population? o • What two components control the variation of traits? o • What two components define a species? o • What is the allele frequency? o EVEN MORE: • What is genetic equilibrium? o • What is a mutation and how does it affect genetic equilibrium? o • • What is immigration and emigration and how do they affect genetic equilibrium? o What is genetic drift and how does it affect genetic equilibrium? o • What is the most important factor altering genetic equilibrium? o TYPES OF SELECTION: • Draw the diagram for stabilizing selection and explain. o • Draw the diagram for directional selection and explain. o • Draw the diagram for disruptive selection and explain. o • • What is sexual selection? o What is the most commontype of selection? o OTHER: • What must happen in order for speciation to occur? o • What is geographic isolation and how does it affect a species? o • What is reproductive isolation and how does it affect a species? o • Compare and contrast gradual and punctuated equilibrium. o • What does the word extinct mean? o THEORIES: • Explain Lamarck's theory of Inheritance of Acquired Characteristics o • What did Darwin call the process by which organisms with favorable variations survive and reproduce at a higher rata? o • What does "decent with modification" mean? o • What do we call the ptarmigan's ability to turn white in the winter in order to blend with the snow? o • Darwin believed that all organisms were derived from what? o
